  • Patent number: 7336173
    Abstract: The Owner Aware Object represents a new class of Physical Objects that mimic the awareness of the presence or absence in their immediate surroundings of their rightful owner. The system is composed of an Owner Private Space Generator, one or multiple Owner Private Space Sensors and an optional Super Owner Aware Object which is a Computer connected Owner Aware Object. The Generator and the Sensor Objects work together to establish within a three dimensional space, a volume of Object and Owner Security. While within this volume, the Sensor is maintaining ciphered communication link with the Generator and thus establishes a Secure Volume. Should these two components lose this link, a breach of security event is triggered and both units attempt Owner Notification of the new state of the system. Should two or more Owner Private Spaces intersect or collide, all Owners are notified of the new system status.

  • Patent number: 5065151
    Abstract: An apparatus and method for switching video signals from input lines to output lines. A control device selectively sets a blackout start time and a blackout stop time. A first comparator compares the blackout start time with actual time and a second comparator compares the blackout stop time with actual time. A switch is provided for connecting the input lines to output lines and for disconnecting the input lines from the output lines. The switch is responsive to the first comparator to disconnect all input lines from all output lines when the actual time equals the blackout start time. The switch is also responsive to the second comparator to reconnect the input lines to the output lines when the actual time equals the blackout stop time.
